Teeth Bleaching Whitening, 35% Gel Syringes, Free Shade Guide, 40 mL (4)

Seems to work well. Excellent value. Taste doesn’t bother me and sensitivity is not really a big deal and is no worse than the one I got from my dentist. My only complaint is that the nozzle opening (orifice) is quite large and it’s very difficult to dispense an appropriate amount. I usually have to spread the gel around after putting too much in one tooth pocket.

This stuff tastes so bad that it's nauseating. I've used several brands of whitening gel and they were all fine, but this stuff is horrible. It not only tasted really bade when I put in the trays, but it also made me salivate a great deal and because of that I probably swallowed some of it. As a result, it also made me feel sick. Unfortunately, I ordered as soon as I used up what I had (from a different vendor) and so by the time I tried this, it was beyond the return window. So, what might have been a bargain, has turned out to be a total waste of money because I can't use this stuff.
